Definitions

  • the disclosure relates to the field of intelligent network communications in an IP Multimedia Subsystem (IMS) and a Next Generation Network (NGN), to Click To Dial (CTD) and a broadcast group call, and particularly to a method and system for implementing a broadcast group call in a CTD service.
  • IMS IP Multimedia Subsystem
  • NTN Next Generation Network
  • CTD Click To Dial
  • the so-called CTD service is the click to dial service.
  • a user logs in to a CTD WEB interface and inputs a logical calling number of such as a user A and a logical called number of such as a user B; a CTD application server first calls the logical calling number of the user A; after A picks up, the CTD application server then calls the logical called number of the user B; the logical called number B rings, A listens to the ringback tone, B goes off-hook, and A and B talk.
  • the CTD service is a call-type service by which the telephone numbers of two parties between whom a user wish to conduct a conversation are bridged, so as to realize the conversion between the two parties.
  • the so-called broadcast group call means that the logical calling number of the user A simultaneously talks to multiple logical called numbers of users B1, B2 and so on. However, only the logical calling number user A can speak, the logical called number users B1, B2 and so on themselves cannot speak and can only hear the speech of the user A, which is similar to the broadcast in reality; while the call is initiated simultaneously to the users B1, B2 and so on, so it is also called as a group call.
  • the user A may also designate one of some users such as a user Bi as a chairman, such that both of the user A and the user Bi can speak.
  • the user A may also conduct a paged private chat with one of some users such as a user Bk, such that the user A and the user Bk conduct a private chat individually, and other users continue to maintain the original status.
  • a user may continue to speak if he/she is designated as the chairman, and continues to listen to someone else's speech if not.
  • a conventional calling service is implemented by the user to directly dial a destination telephone number via a terminal (such as a fixed telephone, a cell phone and so on).
  • a terminal such as a fixed telephone, a cell phone and so on.
  • CTD calling is a calling in which the CTD application server separately initiates two paths of telephone numbers which need to conduct a conversation.
  • the conventional CTD service is widely used in modern communication networks, for example, WebCall, Web800 and so on all belong to the CTD calling service or derived services thereof.
  • the user may view, through an operation interface of the CTD calling, a status of the current conversation (such as the telephone numbers and names of both parties of the conversation), and a status of the call (for example, a callee is ringing, the callee is answering, the callee is on-hook and the callee is placing the call on hold).
  • a callee is ringing, the callee is answering, the callee is on-hook and the callee is placing the call on hold.
  • head portraits used by both parties or the like may be displayed on the interface, and the service may be further extended to implement an Instance Message (IM) service of the both parties of the conversation.
  • IM Instance Message
  • Fig. 1 is an implementing flow of a CTD service, where function of each network element is described as follows.
  • Protocols used in the specific network elements are as follows.
  • Fig. 1 is a diagram of a profile only, and network topologies of the IMS or the NGN are concealed, while the CTD AS, the MRS and the UE access the IMS network or the NGN network in actual implementations.
  • Fig. 2 is a signaling flowchart of conventional CTD services, in which the CTD AS first calls a UE A, and then calls a UE B, and a bridging connection between the UE A and the UE B is established after the two users go off-hook, thereby implementing the conversation between the UE A and the UE B.
  • the conventional CTD service can only implement the conversation between two parties and cannot achieve the broadcast group call.
  • the primary purpose of the disclosure is to provide a method and system for implementing a broadcast group call in a Click To Dial (CTD) service, which is used to resolve the technical problems with the conventional CTD service which cannot implement the group call of multiple logical callees and does not support functions such as broadcasting.
  • CTD Click To Dial
  • a method for implementing a broadcast group call in a click to dial service includes:
  • the method may further include: before the CTD AS associates the logical caller with the MRS, determining, by the CTD AS, whether there is any logical callee in the list of the logical callees goes off-hook, and associating the logical caller with the MRS when determining that any one logical callee in the list of the logical callees goes off-hook; and terminating, by the CTD AS, the calling flow when finally determining that none of the logical callees goes off-hook.
  • the method may further include: playing, by the CTD AS, a ringback tone to the logical caller when the logical caller goes off-hook and the CTD AS determines that a provisional response of at least one logical callee is ringing; and stopping, by the CTD AS, playing the ringback tone to the logical caller after the CTD AS determines that at least one logical callee goes off-hook.
  • the method may further include: designating, by the logical caller, a certain logical callee as a chairman as required, and controlling, by the CTD AS, the logical callee who becomes the chairman to be able to listen and speak; and/or, designating, by the logical caller, a certain logical callee as a private chat object as required, and controlling, by the CTD AS, the logical caller and the logical callee who becomes the private chat object to conduct an individual private chat.
  • the method may further include: reporting, by the CTD AS, current statuses of the logical caller and the logical callees to the CTD WS, and displaying, by the CTD WS, the current statuses of the logical caller and the logical callees for a user.
  • a system for implementing a broadcast group call in a click to dial service which includes a Click To Dial service WEB Server (CTD WS), a Media Resource Server (MRS) and a Click To Dial service Application Server (CTD AS), wherein the CTD WS is configured to send a call request to the CTD AS, wherein the call request comprises a logical caller and a list of logical callees; the CTD AS is configured to call the logical caller and to conduct a group call on all the logical callees in the list of logical callees after the logical caller goes off-hook; and after any one logical callee in the list of logical callees goes off-hook, the CTD AS is further configured to associate the logical caller with the MRS and to control the logical caller to be able to listen and speak, and to associate the logical callees who have currently gone off-hook and will subsequently go off-hook with the MRS and
  • the CTD AS may also be configured to terminate the calling flow when determining that none of the logical callees goes off-hook.
  • the CTD AS may also be configured to: play a ringback tone to the logical caller when the logical caller goes off-hook and the CTD AS determines that a provisional response of at least one logical callee is ringing; and to stop playing the ringback tone to the logical caller after the CTD AS determines that at least one logical callee goes off-hook.
  • the CTD AS may further be configured to control the logical callee who becomes the chairman to be able to listen and speak; and/or, when the logical caller designates a certain logical callee as a private chat object, the CTD AS may further be configured to control the logical caller and the logical callee designated as the private chat object to conduct an individual private chat.
  • the CTD AS may further be configured to report current statuses of the logical caller and the logical callees to the CTD WS; and the CTD WS may further be configured to display the current statuses of the logical caller and the logical callees for a user.
  • the signaling control and conference audio mixing are performed by a click to dial service application server and no specific terminal is required, and the group call and broadcasting of multiple logical callees can be implemented under the control of the click to dial service application server, every logical called user can access the call as long as he/she goes off-hook.
  • the disclosure extends the functions of the existing click to dial service, extends the application of the click to dial service, and satisfies multiple demands of users.
  • Fig. 3 is a flowchart of steps of a method for implementing a broadcast group call based on a CTD service according to the disclosure, and the disclosure is implemented as an extended function of the CTD service, the detailed steps are as follows.
  • Step F1 a user logs into a CTD WEB and clicks to call after inputting a logical caller and a list of logical callees, and a call request is sent by a CTD WS to a CTD AS.
  • Step F2 the CTD AS receives the call request, sends a response accepting the request to the CTD WS, and displays prompt information on the CTD WEB: the call is being processed.
  • Step F3 the CTD AS calls the logical caller A.
  • Step F4 the CTD AS reports a response of the logical caller A to the CTD WS and displays it on the CTD WEB in real time, such as ringing, off-line, busy, off-hook and the like.
  • step F6 is performed if final response of the logical caller A is off-hook. Otherwise, step F5 is performed.
  • Step F5 the CTD WS controls the CTD WEB to display prompt information of failure: the logical caller A has not gone off-hook, the call fails, and the flow ends.
  • Step F6 the CTD AS simultaneously calls all the numbers in the list of logical callees, such as B1, B2....
  • Step F7 the CTD AS reports a response of each logical callee to the CTD WS and displays them on the CTD WEB in columns in real-time, such as ringing, off-line, busy, off-hook and the like.
  • Step J2 step F8 is performed if provisional response of at least one logical callee is ringing. Otherwise, step J3 is performed.
  • Step F8 the CTD AS plays a ringback tone to the logical caller A, and brief service prompt information is included.
  • Step J3 if none of final responses of the logical callees is off-hook, step F9 is performed. Otherwise, step F11 is performed.
  • Step F9 the CTD WS controls the CTD WEB to display prompt information of failure: none of the logical callees is off-hook, and the call fails.
  • Step F10 the CTD AS plays prompt tone of failure to the logical caller A: none of the logical callees is off-hook, the call fails, and the flow ends.
  • Step F11 the CTD AS stops playing the ringback tone to the logical caller A.
  • Step F12 the CTD AS associates the logical caller A with an MRS and controls A to be able to listen and speak.
  • Step F13 the CTD AS associates the logical callees who go off-hook with the MRS, and controls them to be only able to listen but not able to speak.
  • Step F14 the logical caller A begins to speak, the logical callees who have gone off-hook can hear the speech of A in real time, and the logical callees who will subsequently go off-hook can also hear the speech of A.
  • Step F15 the logical caller A designates a certain logical callee as the chairman as required, and the CTD AS will control the logical callee who becomes the chairman to be able to listen and speak; and/or, the logical caller A designates a certain logical callee B as a private chat object as required, and an individual private chat between the logical caller A and the logical callee B is conducted under the control of the CTD AS, and other users continue to maintain the original status.
  • Fig. 4 is a signaling flowchart for implementing the broadcast group call based on the CTD service provided in the embodiments of the disclosure.
  • A as the logical caller and B1, B2, B3 as the list of logical callees
  • illustrations of the signaling flow for implementing the broadcast group call based on the CTD service are sequentially numbered:
  • an embodiment of the disclosure also provides a system for implementing a broadcast group call in a click to dial service, module functional structure of this system may still be based on the structure of existing CTD service system shown in Fig. 1 , except that functions of the CTD WS, CTD AS and MRS in the existing CTD system are extended in the disclosure, thereby extended functions of group call of multiple logical callees, broadcasting and so on are implemented.
  • the extended parts are all able to be directly derived from the above method flow and signaling flow, which will not be described in detail herein.
  • the method and system provided in the embodiments of the disclosure can implement the function of group call of multiple logical callees in the click to dial service, which function belongs to a B2B (Back to Back) calling type service, the advantages of which are:
  • the signaling control and conference mixing are performed by a click to dial service application server and no specific terminal is required, and the group call and broadcasting of multiple logical callees can be implemented under the control of the click to dial service application server, every logical called user can access the call as long as he/she goes off-hook.
  • the disclosure extends the functions of the existing click to dial service, extends the application of the click to dial service, and satisfies multiple demands of users.
